To find the equation of the line that passes through the point $(-7, -8)$ and has a slope of 0:

1. A line with a slope of 0 is horizontal. Therefore, the y-value is constant for all points on the line.

2. The equation of a horizontal line passing through a point $(x, y)$ is $y = c$, where $c$ is the constant y-value.

3. For the point $(-7, -8)$, the y-coordinate is $-8$. Hence, the equation of the line is: $y = -8$

Here are 5 related questions to extend your understanding:

1. What is the equation of a vertical line passing through a specific point?
2. How do you determine the slope of a line from two given points?
3. How can you find the equation of a line with a nonzero slope?
4. What are the general forms of linear equations, and when is each used?
5. How do horizontal and vertical lines relate to the concept of slope?

Tip: A horizontal line always has a slope of 0, and its equation is determined solely by the y-coordinate.
